觀察細節
Surprised at the number of (likely) SY individuals present, but maybe this is normal. SY traits include combination of "nonbreeding" head pattern, mostly dark bill, delayed outer pp molt compared to older ages (one definite SY with retained juvenile outer pp, others growing p10). 2-3 individuals had completely dropped median coverts.
